The default CentOS version of 2.3 is ancient in Postfix years. :) Google "postfix centos 2.8" and a howto I wrote will pop up as the top hit. All settings from your current Postfix install will be maintained. SteveJ

Is not ok to test mail server configuration on virtual machine even for sending only cause I don't have mx record for this domain I just test configuration Regards I think that Yahoo, as well as Hotmail, probably AOL has some type of hardware which blocks certain types of connections. And yahoo isn't known to be easy to getting any answers from, somewhat like winning the lottery, unfortunately. However they do wide range of tests to make sure connection is genuine, therefore to rule out misconfiguration on your side a fully functional dns is recomended. If you can give some more info how your setup looks like, and if yahoo specific is the problem, perhaps anyone will be able to help you to dig into the problem. Andreas
